Erbium
Erbium, with the chemical symbol Er and atomic number 68, was discovered in 1843 by the Swedish chemist Carl Gustaf Mosander. Mosander extracted it from the mineral yttrium erbium phosphate and named it after the village of Ytterby in Sweden, a significant source of rare earth elements.
Although erbium is relatively rare on Earth, constituting about 0.00003% of the Earth's crust, it plays a crucial role in various technologies. Its notable application lies in telecommunications, specifically in fiber optic amplifiers. Erbium-doped fibers are used in optical amplifiers to enable data transmission over long distances.
The production route of erbium begins with extraction from minerals such as monazite, xenotime, and gadolinite, which contain rare earths. Through complex chemical processes, including extraction and crystallization, pure erbium is isolated.
The future of erbium extends beyond telecommunications, with ongoing research exploring its applications in medicine, particularly in laser technology for tissue ablation and surgery.
